The standard way for manufacturers to measure bag volume is by filling with small balls of a particular size. Different bag shapes, construction, and layout will give different volumes for the same dimensions, especially if there are more compartments can reduce the amount of balls. Maybe the Airboss losses space with thicker materials or more internal panels or maybe they are using non-standard measurement ways.
Also, how about the MEI convertible or MEI Executive overnighter for your comparison?
